Smart-Fire FITTING INSTRUCTIONS

WARNING: THIS SYSTEM PRODUCES VERY HIGH VOLTAGES, ALWAYS SWITCH OFF BEFORE WORKING ON THE SYSTEM.

Before fitting, please read these instructions carefully, including the notice on page 16. This system is designed to work only with the special digital ignition coils provided with the system. 5K resistor plug caps as supplied with the system should be fitted to the h.t. leads. Alternatively, resistor spark plugs can be used. Attempting to run the system without resistor type caps or plugs will result in excessive radio frequency interference (r.f.i.), which may cause bad running, misfiring and loss of ignition. For reliability, copper or steel cored h.t. lead should be used, we do not recommend using carbon fibre leads. This ignition is a wasted spark system, therefore all plugs fire at the same time. These instructions are a general guide for installing the system to various machines and therefore it may be necessary to modify the length or routing of some wires in order to complete the installation. All connections should be made using good quality crimped or soldered connections; twisted wires will not give satisfactory operation. Wiring should be trimmed to the correct length, excess wire should not be coiled up as this can affect the correct running of the ignition system. If electric welding is to be carried out, the ignition module should be disconnected and its connectors covered with insulation, to help prevent stray sparks from damaging the module. If in doubt, remove the unit from the machine. 1. Disconnect the battery. 2. Remove the timing cover and automatic timing device (if fitted). 3. Remove the magneto cowl and magneto. Fit the magneto

replacement unit in place of the magneto (using the original fixings). The long nut may need to be waisted (reduced in diameter) in order to clear the body.

4. Fit the ignition module in a convenient place, preferably under the battery platform, or behind the magneto cowl. The unit can be orientated in any position, but this should be onto a flat surface, if

3

possible. Secure the unit by the mounting flanges using the two M5 bolts, shakeproof washers & nuts. Alternatively, the mounting flanges can be removed by slackening the bracket securing screws and sliding the brackets out of the dovetail slots. The module can then be mounted using large tie-straps, with a small sheet of rubber between the case & the frame.

5. Fit the ignition coils in a convenient place, where possible away from the ignition module & magneto replacement unit. Suspend each coil by the two mounting lugs, using the M5 bolts, washers & nuts. Alternatively, to avoid the need for drilling or a mounting bracket, each coil can be rubber mounted using two small pieces of rubber tubing (such as fuel pipe or heater hose) & two large tie-straps, see figs. 1 / 1a. The coils can then be secured by passing the tie-straps around the frame tube & fully tightening the tie-straps. Fit the new h.t. leads by pushing the brass connectors fully into the h.t. outlets of the coil, along with the rubber boots. Small tie-straps can be placed around the rubber boots & tightened to give extra security, if desired. The h.t. leads should now be cut to length, if necessary, & the plug caps screwed onto the ends of the h.t. leads. The h.t. leads should be arranged so that each coil fires across both cylinders. Push the plug caps firmly onto the plugs, they should click into place.

WIRING (PLEASE SEE WIRING SCHEMATICS ON PAGES 8 & 9) 1. The ignition trigger wires (sleeved) are coloured: white—red, violet—red, white—black & yellow—green. Allowing some slack in the cable, route these wires down to the magneto replacement housing, remove the housing cap & feed through the grommet in the cap. Route the wires around to the ignition trigger 4-way connector block. Allowing some movement in the cable (for setting the ignition timing), cut the cable & sleeving to length. Carefully strip back 4-5mm of insulation from the ends of the four wires. Insert the four wires into the connector block (from left to right) as follows: white-red, violet-red, white-black & yellow-green. Tighten the four screws with a small screwdriver. Secure the sleeved wires to the trigger plate with two small tie-straps, using the two sets of holes provided. See fig. 3, page 12. 2. Connect the violet wire from the ignition module to the negative (—)

terminal (left-hand spade connector) of the first ignition coil (#1), using a female crimp connector and insulating cover.

3. Connect the red wire from the ignition module to the positive (+) terminal of the second (#2) ignition coil (right-hand spade connec-tor), using a female piggyback crimp connector and insulating cover.

4. Using the black coil link wire, connect the positive (+) terminal of the first ignition coil to the negative (-) terminal of the second ignition coil. See pages 8 & 9.

Re-check the connections to the ignition coil;

reverse polarity may damage the coil. For positive ground electrics, please go to step 6. 5. For negative ground electrics: connect the black wire from the ignition module to a good grounding point on the frame or directly to the battery negative (—), using a ring terminal. Connect the spare terminal on the piggyback connector (on the positive side of the second (#2) ignition coil), to a switched positive supply (+12

6

volts), preferably via a fuse (8-10 amp recommended) and through the ammeter (if fitted). Go to step 8. 6. For positive ground electrics: connect the spare terminal on the piggyback connector (on the positive side of the ignition coil) to a good grounding point on the frame or directly to the battery positive (+), using the red grounding wire provided. Connect this wire to the coil end using a female spade connector and insulating cover. Connect the other end to ground using a ring terminal. 7. Connect the black wire from the ignition module, to a switched

negative supply, preferably via a fuse (8-10 amp. Recommended) and through the ammeter (if fitted).

8. Suggestions for the choice of switch can be a spare position on the headlamp switch (if available), a second dip switch on the handle-bars or a key switch located in the headlamp shell. It is important that the switch is in good condition; corroded or dirty contacts will cause misfiring/cutting out.

9. The ORANGE wire is an ignition inhibit input. This can be connected to a grounding kill switch or a hidden security switch, provided that the vehicle is negative ground.

If not required, place insulating tape over the end of the wire to prevent shorting out. 10. The GREY wire is a tacho output signal for driving an electronic

tachometer, if fitted. This is a 12 volt pulsed output and provides 1 pulse per two engine revolutions (0.5 pulses/rev). If your tacho requires a different pulse rate, contact Pazon Ignitions. Connect to the tacho signal input terminal/wire. If you have a mechanical tacho, an inductive pickup tacho (e.g. Scitsu) or no tacho, then leave unconnected; cut short the wire & and insulate the wire end.

11. Any remaining wires which may be present on the ignition module are for factory use and should remain unconnected and insulated, as supplied.

TIMING (PLEASE SEE PAGE 12/13, FIGS. 2 - 5) 1. Switch off ignition or disconnect the battery. 2. The automatic advance unit is no longer required and should be

removed. However, if it is to remain in place it must be locked solid by whatever method is available. The preferred alternative is to replace the automatic advance unit with a solid drive pinion, please contact your dealer for the necessary parts, if required. The ignition module includes electronic advance/retard suited to the Vincent engine, with twinplug head conversion.

3. Remove spark plugs. Set the rear piston at TDC (top dead centre) on the compression stroke.

4. Remove the cover from the magneto replacement unit. 5. Undo and remove the trigger plate hex pillar fixings & washers and

place in a small container for safe keeping. 6. Lift out the trigger plate to expose the steel timing disc. 7. Slacken the centre screw using a 3/16” hex key. 8. Rotate the timing disc until it is as shown in fig. 2. With the two

holes at 12 o’clock & 7 o’clock. Tighten the centre screw & re-check the position.

9. Refit the trigger plate, washers and hex pillar screws previously removed in step 5, turn them down using only your fingers, so that the plate can be rotated by hand.

10. The following operations may produce a spark from the plugs, therefore it is recommended that the spark plugs be removed and grounded onto the cylinder head (with the plug caps & h.t. leads connected to them). Alternatively, the violet wire can be temporarily disconnected from the negative terminal of the ignition coil, place insulating tape over the end of the connector to prevent shorting to ground. This will prevent any undesired sparks whilst timing.

11. (Reconnect battery). • Position the trigger plate in the fully clockwise position. See fig. 4 • Switch the ignition on, the small green light on the ignition

module should flash once and then stay on continuously. The red timing light on the trigger plate should be on.

• Turn the trigger plate slowly anti-clockwise until the red timing light turns OFF, stop turning. This is the timing point for TDC on the rear cylinder. See fig. 5

• Keeping the trigger in position, finger tighten the pillar fixings.

10

• If you make a mistake, switch the ignition off and restart from the beginning of step 11.

• Note the final position of the timing hole at approximately the 7 o’clock position, visible through the inspection window.

12. Tighten the hex pillar fixings using a 7mm hex driver or spanner. Do not over-tighten or the trigger plate may become distorted.

13. Switch off the ignition. 14. Replace the cover on the magneto replacement unit. 15. Refit the spark plugs & caps, if removed earlier. Reconnect the

violet wire to the ignition coil, if disconnected in step 10. 16. The engine should now start and after warming up should tick over

well, provided everything else is correctly adjusted. Strobe timing is not necessary. The ignition will advance as per the pre-programmed curve (see advance graph).

Installation is now complete.

REV-LIMITER USE OF THIS FUNCTION IS AT YOUR OWN RISK, SINCE IT IS POSSIBLE TO SET THE REV-LIMITER TO BEYOND THE DESIGNED UPPER RPM LIMIT FOR YOUR ENGINE. The Smart-Fire ignition module features a function button that enables the user to set/reset the ignition rev-limiter. Unless specified when purchasing the system, the rev-limiter is not preset, allowing your engine to rev to its maximum (unrestricted). To Set the Rev-Limiter To accurately set the rev-limiter you will need a rev-counter/tachometer to monitor the engine rpm. Rev the engine to one-half the desired rev-limit rpm, press & hold the function button for a minimum of 3 seconds. The ignition module will take a snapshot of the engine rpm at the instant the button is pressed, therefore it is not essential to maintain a precise rpm whilst the button is pressed. The yellow indicator led on the module will flash 5 times Release the button. The rev-limiter is now set. When your engine reaches the preset rpm the ignition will turn off the ignition coil, cutting all sparks. Thus, the engine rpm will fall and, once below the rev-limit setting, ignition will resume. The minimum rev-limiter setting is 3000 rpm (i.e. set with the engine running at 1500 rpm). To Reset the Rev-Limiter To reset (disable) the ignition rev-limiter, press & hold the function button for a minimum of 3 seconds, with the engine below 1500 rpm (or stationary). The yellow indicator led on the module will flash 5 times. Release the button. The rev-limiter is now reset. The rev-limiter setting is retained in the ignition module memory & will be recalled when the ignition is turned on.
